AI Article Synopsis
- A heart-shaped nanocomposite (MXenen@Cu-MOF, MC) was created to enhance electrical conductivity and antibacterial properties, preventing MXene accumulation.
- The composite is integrated into Polyvinyl alcohol/Poly-dopamine hydrogel wound dressings (PPMC), which can break down bacterial biofilms and support electrical currents for faster wound healing.
- PPMC0.2 demonstrated superior performance with a healthy balance of biocompatibility, achieving a cell mobility of 58% in 24 hours and an 81.84% wound healing rate in 6 days, outperforming other samples and providing a promising treatment approach for chronic wounds.
Article Abstract
In this paper, a heart-shaped nanocomposite (MXenen@Cu-MOF, MC) has been prepared by hydrothermal method. This material can effectively prevent the accumulation of MXene, improve the material's electrical conductivity and antibacterial properties. In addition, it is loaded into Polyvinyl alcohol/Poly-dopamine hydrogel wound dressings (PPMC), which can effectively destroy bacterial biofilms and provide a new pathway for internal electrical currents, helping to repair internal electric fields and promote wound healing. Through the concentration gradient experiments of hydrogel such as antibacterial, conductive, hemolysis and cell migration, we believe that the addition of MC can improve the basic properties of hydrogel. Among them, PPMC0.2 is the hydrogel with the best performance under the premise of meeting bio-compatibility. Its resistance, between 500 and 1000 Ω, is lower than the skin resistance at the wound site and provides the basis for the passage of current through the body. In addition, the cell mobility (24h) of PPMC0.2 reached 58%, and the wound healing rate (6day) was 81.84%, which was much higher than that of other experimental groups. The experimental results proved that PPMC hydrogel can promote wound healing, and this study also provided a new therapeutic idea for chronic wound healing.

Background: Understanding healing of the alveolar process is crucial for immediate implant, alveolar ridge preservation and guided bone regeneration procedures, and to evaluate it several different scales have been proposed; however, all have different characteristics and seem to miss a standardization allowing for an objective and dichotomous evaluation of the different aspects of wound healing. The objective of the present study is to propose and apply, in real clinical scenarios, a novel index for the objective evaluation of wound healing following erupted tooth extraction.
Methods: Healthy patients in need of a single tooth extraction were enrolled and re-examined at 7, 14 and 21 days after the extraction using the novel index proposed.

Wound healing is a complex and dynamic biological process that requires meticulous management to ensure optimal outcomes. Traditional wound dressings, such as gauze and bandages, although commonly used, often fall short in their frequent need for replacement, lack of real-time monitoring and absence of anti-inflammatory and antibacterial properties, which can lead to increased risk of infection and delayed healing. Here, we address these limitations by introducing an innovative hydrogel dressing, named PHDNN6, to combine wireless Bluetooth temperature monitoring and light-triggered nitric oxide (NO) release to enhance wound healing and management.

Uncontrolled bleeding and infection following trauma continue to pose significant clinical challenges. This study employs hemoadhican (HD) polysaccharide, known for its superior hemostatic properties, as the foundational material to synthesize antibacterial carbon dots (H-CDs) through a hydrothermal method at various temperatures. The H-CDs exhibiting optimal antimicrobial properties were identified via in vitro antimicrobial characterization.

Dry eye disease (DED) is one of the most commonly diagnosed eye disorders, with a prevalence ranging from 5 to 50%, depending on the geographic location. DED is a multifactorial disorder of the tears and ocular surface, which results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is also accompanied by increased osmolarity of the tear film and inflammation of the surface of the eye.
